Do not start microzed board on power on.

Former Member

Hello,
We have board AES-Z7MB-7Z020-SOM-G, made a program in FREERTOS, created the boot.bin and boot.mcs.
Downloaded a program in QSPI memory and microSD card.
When you first turn runs the FSBL, the PL is configured, but the ZYNQ processor does not start.
When re-turning on the device starts normally.

Moreover, the Board behaves the same when loaded with both QSPI and microSD card.

Why may not start the program?

    You don't give us a lot of information to work with. When you post a question you should always include links to any example or app note your are using, the version of Xilinx tools that example targeted, as well as the version of Xilinx tools you are currently using and your host PC OS.

     

    Have you made sure that you understand the process for generating a bootable image for your MicroZed and that your hardware works correctly? A good check would be to work through the MicroZed Tutorials 01-04 found here:

    You should make sure that, when you are creating your Boot Image in the SDK, you add the files in your boot image partitions in the correct order. It is important that your 'fsbl.elf' is first, followed by your "bitstream.bit" file, and then add the FreeRTOS.elf file last.

     

    You should also check and make sure that the FreeRTOS executable you have generated works correctly by loading it via JTAG with the SDK before trying a bootable version.

    I'm work in vivado 2015.4.
    The boot.bin and boot.mcs created like here: http://zedboard.org/support/design/1519/10 starts and works normally.

    I'm generated like, only my program is based on FreeRTOS. When you first turn power on: runs the FSBL, the PL is configured, but the ZYNQ processor does not start. When re-turning power, the device starts normally.

    So if the program starts, it works flawlessly.

    If the program is downloaded via JTAG, it runs just as well.
